CAR-AXLE BOX.

EPECIPICATION forming part of Letters Patent No. 299,129, dated May 27, 1884.

Application filed November 3, 1883. (No model.)

To all whom it may concern:

Be it known that I, NATHAN M. GEORGE, of Danbury, in the county of Fairfield and State of Connecticut, have invented a new and useful Improved Dust-Guard for (lax-Axle Boxes, of which the following is a specification.

This invention relates to dust-guards for excluding the dust from car-axle boxes or other vehicles where the nature of the invention will admit ofits use.

The principal feature of this invention is the construction and arrangement of the apertured board and thin pieces of leather, vulcanized fiber, or other suitable material in such a manner as will close the opening encircling the axle without producing excessive friction against the axles, which causes them to wear away rapidly and renders them useless, as will be hereinafter more fully explained.

In the accompanying drawings, forming part of this specification, Figure 1 represents a sectional side elevation of my improved dust-guard, showing the apertured board and leather cl 0 in place. The apertured board is made of wood, and the other is usually made of vulcanized fiber or leather. The board is operated by a spring which is placed in the bottom of the box, and is for the purpose of receiving the weight of the board and to keep it up close to the lower side of the axle. This spring 6 is made usually of thin steel wire, and is sufficiently stiff to keep the board up close to the lower side of the axle without me ating friction. The apertured wooden board d, which is made quite thick and heavy, rests against the spring 6, and will thus adapt itself to the vertical movement of the axle, and

at the same time keep the opening closed on the lower side. The apertured piece 0 is made very thin and light, so that its weight on the upper side of the axle will cause no friction. The thin piece a is left free, and will rest loosely upon the upper side of the axle, thus effectively closing the entire opening. It is also made shorter than the apertured board (I, so that its lower end will'not come in contact with the spring 0 and prevent its operation.

Fig. 2 is a transverse section through the line a :0, Fig. 1; to show the spring 6 and apertured board (Z partly broken away. Apertured boards that have been used heretofore were objectionable, because they created too much friction against the axle, and would wear-out in a very short time and become useless.

Having thus described my invention,what I claim as new, and desire Patent, is-

A dust-guard for car-axle boxes, substantially as herein described, consisting of one apertured board, d, and athin apertured piece, 0, made of vulcanized fiber or leather, as described, the wooden board d having a spring, 6, operated against its lower end, as described, and for the purpose herein specified.

In testimony that I claim the foregoing imto secure by Letters proved dust-guard for car-axle boxes, as above described, I have hereunto 12th day of October, 1883.

NATHAN M. GEORGE.
